SELF-CLOSING GAS-BURNER.

SPECIFICATION forming part of Letters Patent 0. 598,892, dated February15, 1898.

Application filed October 9, 1897- To aZZ whom it. may concern.-

Be it known that I, FRANK P. BARNEY, a citizen of the United States,residing in Norton, in the county of Bristol and State of Massachusetts,have invented new and useful Improvements in Self-Closing Gas-Burners,of which the following is a specification.

This invention relates to a novel and improved construction whereby onthe extinguishing of the flame the gas will be automatically shut offand on the application of a jet of flame-as from a burning match, forexample-the gas will be automatically turned on; and the invention isintended to be an improvement over and upon the invention described andillustrated in Letters Patent of the United States granted July 6, 1897,and numbered 585,902.

The nature of the invention or improvement is fully described in detailbelow and illustrated in the accompanying drawings, in which- Figure 1is an elevation of my improved gas-burn er. Fig. 2 is a plan view of thesame. Fig. 3 is a part elevation and part longitudinal vertical sectionof the same. Fig. 4 is a detail in section taken on line X, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the burner proper, and a the b is the gas-inlet.

Extending diagonally upward from the burner A on one side is a bracketB, which may be solid or tubular, as desired. Extending diagonallyupward on the opposite side of the burner at substantially the sameangle as the bracket B is a bracket 0. The upper end 0 of this bracketis enlarged and is providedwith a horizontal chamber so counterbored asto be divided into the large chamber D and the smaller chamber E, bothof which are preferably or approximately round in cross verticalsection. The outer end of the chamber D is closed by means of the plug6. The tip a is set into a chamber or socket. F, which does not directlyconnect with the inlet b, but which is connected by the passage H in thebracket 0 with the chamber E. The inlet b is connected by a passage K inthe bracket 0 with the chamber D. A valve-disk L is in the chamber D,and being larger in- Serial No. 654,610. (No model-J lic wire S extendsfrom this valve-disk horizontally through a suitable opening in theupper portion 0 of the bracket 0 into the upper portion B of the bracketB, its end being held rigidly within said portion B by a binding-screwP. The brackets B C are so set with relation to the burner A that thewire intersects and extends across the burner on a line a trifle oneside of the center of the tip, as seen in Fig. 2, so that were the slotat in the tip made parallel with the wire it would not be exactly underit. When the right end of the wire is inserted in its socket in the partB, the binding-screw P is set against it, and being so placed withrelation to the wire that its center is below said wire the screw whenturned to the right operates'to stretch and make taut the wire and drawthe Valvedisk L against its seat D.

I To light the burner, apply a flame, as from a lighted match, to thewire S and it will expand and move the valve-disk L from its seat, thusconnecting the chambers D and E. The gas then flows from the inlet 1)through the passage K, chambers D and E, and passage H into the chamberF, and thence to the tip a, when it is ignited by the flame. Should theflame from the tip be blown out, the wire S contracts and draws thevalve-disk L against itsrseat D, and thus shuts off the supply of gas. I

As above mentioned, the tip is so set with relation to the wire that thewire does not ex the drawings that the tip is so turned that the slotextends diagonally across the wire. The position of the tip withrelation to the wire prevents the blaze from being out or divided intotwo equal parts, and the angle of the slot serves to apply to the wirejust the proper heat. If the slot were at right angles with the wire,there would be too little heat, inasmuch as the side of the flame wouldnot radiate much heat toward the wire. On the other hand, if the slotwere turned so as to be ata very acute angle with the wire the flamewould present too much heat to the wire.

too

chamber on opposite sides of the valve-seat respectively with thechamber F and the gasinlet; a valve within said horizontal chamber;

a Wire extending therefrom over the burnertip on one side of its centerto the opposite bracket; and a binding-screw set against the Wire sothat the wire intersects its binding end on one side only, thus enablingthe screw to tighten the wire as it is turned, substantially asdescribed.
